Subject: [PATCH net-next] net/x25: Remove unused x25_terminate_link()

From: "Dr. David Alan Gilbert" <linux@...blig.org>

x25_terminate_link() has been unused since the last use was removed
in 2020 by:
commit 7eed751b3b2a ("net/x25: handle additional netdev events")

Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
